Hi, it's reasonably common for the Honda Bluetooth modules to cause power drain issues, I've diagnosed and seen a few myself also.
The 2006 version of Bluetooth, as you describe it, will not support the same Bluetooth profiles and functions as a modern unit and there are no retrofit options for a more modern unit that I am aware of.
Functions like music streaming via Bluetooth, etc, wouldn't be available as they would in more modern equipment.
Depending on the cost, i'd be inclined to just have the module unplugged, no more drain issues then get an aftermarket kit fitted away from the dealer!
I have the uk version of the Honda crv, the Bluetooth hands free phone book is irritating and it doesn't like taking calls initiated from the handset!
